our password manager holds the keys to your entire life: your bank, your email, your business, all of it. So what happens to it if you're gone? A break-glass kit is the one document that gets the person you trust into your accounts, without leaving the keys lying around. Here's how to build one in Killswitch, plus a real example to copy.

Most founders keep the whole business in their head — until the day they're not there. A handoff journal documents how the company actually runs (access, money, people, operations) so your team or family isn't locked out if you're suddenly gone. Here's how to build one in Killswitch, plus a real example to copy.

Killswitch now connects to Claude. Ask it to draft notes and notebooks for you — everything stays encrypted at rest, and Claude only has access during sessions you start and can revoke.

Google's BeyondCorp paper introduced zero trust to enterprise security in 2014. The same framework — identity over location, authentication as perimeter, least privilege, assume breach — ports directly to personal life and produces a better result than the ad-hoc alternative.

Bruce Schneier, Edward Snowden, and Cory Doctorow have spent careers writing about personal threat modeling against state surveillance and platform power. Their principles apply more cleanly to digital estate planning than most estate-planning advice does. A walk-through.

Engineering teams run tabletop exercises to rehearse disaster scenarios before they happen. The same practice applies cleanly to families and estate planning. Three scenarios, the gaps they'll surface, and how to facilitate the exercise so it actually surfaces them.

Microsoft's STRIDE framework was built for application security. It works just as well on personal OPSEC and estate planning — spoofing your identity, tampering with beneficiary designations, denial of service on your own life. A walk-through.

Birthdays, weddings, anniversaries — the messages you want to reach your family at moments you won't see. A practical guide to formats, triggers, and storage for sending messages decades into the future, plus the advice you actually need to start.

The check-in window on a deadman switch is a probability trade-off between false positives (firing while you're alive) and false negatives (not firing when you should). The honest math, and why the right cadence depends on more than just the slider in the settings.

Some things land better in your own voice than in a paragraph that reads like a legal memo. Notebook entries can now be video or audio messages — recorded in-app, encrypted at rest the moment they're stored, and delivered with the rest of your plan. Plus a rebuilt, full-screen recorder and a smoother notebook editor on mobile.
